ADJUSTING BEVIQE FOR LEATHER-SPLITTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 75 5,761, datedlflarch29, 1904.

Application file d June 26, 1903. Serial No. 163,259- (No model.)

To all whom it nuty concern.-

Be it known that we, JOSEPH H. GAY and WILLIAM D. QUIGLEY, of Newark,Essex county, New Jersey, have Invented a new and useful Improvement inAdjusting Devices for bars disposed on opposite sides thereof andbearing against the same and conjointly adjustable to move said rolllaterally.

In the accompanying drawing, 1 is the bed of the machine, having sidebrackets 2, in which are adjusting-screws 3. On the bed and between saidscrews is a platform l, which may be moved transversely said bed bymeans of said screws. In said platform is a slot 5, through which passesthe clamping-screws 6 entering the bed. By means of said screw 6, saidplatform may be held in adjusted position. Secured upon the movableplatform 4 are standards, two of which are shown at 7 and 8. Uponstandard 7 is secured the inclined bar 9. On the standard 8 is a bar 11,having clamping-screws, as 12, and adjustingscrews 13, by means of whichit can be adjusted level or at any desired small inclination. The bars 9and 11 form tables which receive the incoming hide and the lower split.The upper edge 14: of bar 9 is beveled on the under side. The rear edge15 of bar 11 is concave. The free spring-roll 16 is located, as shown,between the edges of bars 9 and 11. The form of spring-roll hereillustrated is that fully set forth in Letters Patent No. 7 27 ,838,granted to us May 12, 1903, and consists of a close helix of wireforming a cylinder and supported on a suitable shaft. Below thespring-roll 16 is a driving-roll 17, having an elastic inclosing sleeve18 in contact with said spring-roll 16, so that by the rotation of saiddriving-roll said spring-roll is revolved in the direction of arrow 60,as described in our patent aforesaid.

Above the spring-roll 16 is the gage-roll 19. Usually said roll isreceived between solid jaws, such as 20. Inasmuch, however, as thelateral thrust of the roll due to its direction of rotation and place ofcontact with the hide is in the direction of the arrow 0, we omit therear jaw,.using only one solid jaw 20 as an abutment to receive saidthrust. ,In place of the omitted jaw we substitute a spring-blade 21,supported at an inclination, with its edge bearing on the rollperiphery. The function of said blade 21 is to prevent green or softhide after becoming split fromadhering to the roll-surface, and sobecoming wound on the roll. 22 is a splitting-knife of any suitableconstruction and placed in suitable relation to the rolls 16 and 19,which receive the hide between them and convey it in the direction ofarrow d to the knife-edge, where it is split in the usual way.

From the foregoing it will be seen that the inclined bar 9 andhorizontal bar 11 are supported independently of the rolls upon thetransversely-movable platform 4. In this way the spring-roll 16 may beadjusted with nicety with reference to the gage-roll 19. The hide Amoves in the direction of the arrow at and is split by the knife, asshown. The bars 9 and 11 grasp the spring-roll 16 between them, so that,in fact, said roll is held along three lines of contact all parallel toits axis-namely, at the place of contact g with. the driving-roll and atthe places of contact at the edges 6 f of the bars 9 and 11. Hence inorder to change the position of the roll 16 with reference to thegage-roll 19 it is'only necessary to move the platform 4: in onedirection or the other, the bars continuing to hold the roll 16 alongthe edges 6 f and the rubber surface 18 of driving-roll 17 slightlyyielding to permit of the desired displacement.

The term spring-roll herein means any roll cooperating with thegage-roll in conveying the hide to the knife and is not limited to aroll of elastic or spring material such as here specifically shown.

We claim 1. In combination with a rotary spring-roll, bars disposed onopposite sides of said roll and in contact with said roll and conjointlyadjustable to move said roll laterally.

2. In combination with a rotary spring-roll, bars disposed on oppositesides of said roll and in contact with said roll, and supports IOCcarrying said bars; the said supports being cfinjointly adjustable tomove said roll latera y.

3. In combination with a rotary spring-roll, bars disposed on oppositesides of said roll, and in contact with said roll, supports for saidbars and a platform carrying said supports and adjustable transverselysaid roll.

4. In combination with a rotary spring-roll, a platform disposed belowsaid roll and adj ustable transversely said roll, supports on saidplatform, a bar carried by one of said 6. In combination with agage-roll, a springroll and a driving-roll for said spring-roll arrangedbelow the same, two bars disposed respectively on opposite sides of saidspringroll and in contact therewith and above said driving-roll, andmeans for conjoint-1y adjustirllg said bars to move said spring-rolllatera 1y.

7. In combination with a rotary spring-roll, a bar disposed on the frontside of said roll and having a concave edge, an inclined bar disposed onthe rear side of said roll and having a beveled edge, the said edgesbeing in contact with said-roll, and means for conjointly adjusting saidbars to move said roll laterally. 5

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
